Product boundary
Measurement function, accuracy claims, electrical safety and the conditions under which results are comparable.
Measurand, range, environment, calibration and software. Identify the submitted model, configuration, rated conditions and intended use, including functions crossing other product schedules. This is schedule BESA-S20, edition 1.0, read with BESA 1.0.

The following characteristics identify relevant lines of examination. A characteristic supports recognition only when an applicable European standard or European legal requirement supplies a comparable requirement and the submitted evidence establishes a margin under the programme method. They are not additional European limits.
- Measurement error.
- Repeatability.
- Drift under prescribed conditions.
Use traceable calibration and the relevant uncertainty and decision rule. A smaller nominal error alone is insufficient if the reported interval does not support the comparison.
All other applicable mandatory requirements and baseline checks must be satisfied. At least one selected core comparison must qualify; no scoring or averaging offsets a failure.
Fix the applicable references
Use the linked product-standard research to identify candidate references, then verify the applicable edition, amendments, clause and requirement against the controlled source. The index is a discovery aid and contains earlier editions; a search match alone does not establish applicability or a valid comparison.
Standard references and evidence questions · Official European sources
Record the legal baseline separately from a voluntary standard and identify any relevant Official Journal citation, restriction or transition. IESQ fixes the accepted scope and core characteristics before detailed technical examination.
Product-specific evidence
Submit the technical specification and model matrix, complete reports and amendments, relevant laboratory scopes, the proposed comparison table and the legal documents required for the intended use. For each core claim, identify the report page, requirement, measured result, units, conditions and uncertainty or classification rule. Include adverse findings and retests.
- measurement model
- uncertainty budget
- calibration traceability
- environmental and sample conditions
An additional function may require another schedule and further evidence. Keep the tested specimen connected to the released production specification; declarations and photographs supplement but do not replace the test evidence.
Decision and public scope
The reviewer records whether the required baseline is satisfied and which selected core comparisons, if any, establish a supported margin. A separate authorised person makes the decision. The public record names the particular characteristics, models, configurations, standard editions, validity and limits.
Recognition under this schedule is not approval of every characteristic or of an entire product family. A change affecting measurand, range, environment, calibration and software must be reported for a scope decision.
Prepare your application
IESQ charges no application, examination, certificate, licence, renewal or change fee. Applicants arrange and pay for external testing, translation and other certification services. Recognition is valid for one year and is subject to the current public status.
